No where in the tooltip does it say that this ability bypasses the cover mechanic. it only states that it leaps to the target doing X amount of damage. Is there a dev post saying that this ability, which I would say is classified as a leap, should bypass cover?

It doesn't need to say that. The other ones say that the abilities do not work on a target in cover. Since this tooltip does not contain a similar limitation, it is clear that there are no cover limitations.
